Abstract
A lifting device of a display, is provided. The lifting device includes a stationary member, a lifting member, and an elastic module. The stationary member is suitable for being fixed to a vertical plane. The lifting member is slidably connected to the stationary member. The lifting member is suitable for being fixed to a back portion of the display. The lifting member is suitable for sliding relative to the stationary member between a first position and a second position lower than the first position. The elastic module is coupled between the stationary member and the lifting member. The elastic module is suitable for exerting a pulling force opposite to a gravity direction on the lifting member.
Claims16
A lifting device of a display, the lifting device comprising:
- a stationary member, suitable for being fixed to a vertical plane;
- a lifting member, slidably connected to the stationary member and suitable for being fixed to a back portion of the display;
- and
- a plurality of first springs, disposed on the stationary member and connected to the lifting member;
- at least one frictional resistance module, disposed on the stationary member and contacting the lifting member, wherein the at least one frictional resistance module comprises:
- a base, fixed to the stationary member;
- a friction member, movably disposed on the base and contacting the lifting member;
- and
- at least one elastic member, disposed between the base and the friction member;
- wherein the lifting member slides relative to the stationary member in a vertical direction when the display or the lifting member is subjected to a manual force toward the vertical direction, and the first springs are stretched by the lifting member and exert a first elastic force on the lifting member, wherein the first elastic force is approximate to a weight of the lifting member and a weight of the display;
- wherein the lifting member and the display are held at a height position after the display or the lifting member is no longer subjected to the manual force.
